GUSTAVUS E. TAFT, OF IVHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO THE WHITIN MACHINE WORKS, OF SAME PLACE.

CARDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 233,576, dated October19, 1880.

Application filed March 11, 1880.

To all whom "it may concern:

Be it known that I, GUSTAVUS E. TAFT, of Whitinsville, in the county of\Vorcester and State of Massachusetts, have invented certain new anduseful Improvements in Oarding-liachines, of which the following is aspecification.

My invention relates to machines for carding cotton; and the object ofmy improvement is to obtain with my machine a cotton-sliver of betterquality than usual, and to attain this result with a very small loss ofgood cotton.

Heretofore the most common method of carding cotton has been to have thelarge cylinder r 5 take the cotton direct from the feed-rolls; but as animprovement upon this mode leaders 01' licker-in cylinders have alsobeen used. One objection to these is, that when running at the desiredspeed, too much good cotton is thrown off under the feed-rolls with thedust,

motes, seeds, &c.

The invention will first be described in connection with the drawings,and then pointed out in the claims.

In the drawings, Figure 1 represents a side vie w of a carding-machinehaving my improvements. Fig. 2 represents a front view of the same. Fig.3 represents a longitudinal vertical section of the forward portion ofthe card- 0 ing-machine as made of sheet metal, Fig. 4,

a portion of the same on a larger scale, and with the front casing asconstructed of wood.

In this machine the cylinder A, licker-in 13, workers 0 and O, andfeed-rollers a and a are 5 similar to those commonly used incotton-cards,

and are mounted in adjustable bearings secured to the frame D; but withmy improvement the opening under the licker-in cylinder 13, or betweenthe card-tie or girt E and the worker O, for the escape of dust, motes,trash, &c., is rendered adjustable as follows: The front casing, F, madeeither of sheet metal, as shown in Fig. 3, or of wood, as shown in Fig.4, is hinged to the frame at g and retained in 4 5 position-by pins h,passing through holes (or one of a series of holes, (I, in the two sideframes of the machine) and engaging with or passing in front of theupper portion of said casing F. To the front of this casing is attachedthe dust-box G in such a position under the feed rolls as to receive thedust, motes, &c., released fiect the impurities out of the machine.

(No model.)

from the cotton by the card-clothing of the licker-in cylinder B, andadapted to be easily let down, partly turned over, and emptied of itscontents by turning down nearly the whole 5 5 front casing without beingentirely disconnected from the machine, and without danger to thecard-clothing of the licker-in B in replacing it, as is liable withdust-boxes secured to the frame as heretofore made.

' To the top of the front casing, F, is secured a plate, H, to dividethe air-current and de- This plate is of metal, long enough to extend alittle beyond the edge of the card-clothing, and wide enough to admitofsufticient adjustment as the clothing wears on the licker-in cylinder,and as the licker-in follows up the large cylinder A.

To adjust the plate H its lower edge is provided with a lug, 2', neareach end. These lugs are tapped to receive screws 70, having their stemsgrooved or formed with necks to engage between the branches of forkedstands f, projectingfrom the casing, and be sustained thereby whileadvancing or retracting the plate H. This plate is also connected to thecasing by four or more screws, m, screwed into said casing and passingthrough slots in said plate, to allow the necessary sliding movement ofthe plate when it is desirable to change its position.

I have obtained good results by setting the top edge of the plate aboutfive-sixteenths of an inch from the card-clothing of the lickerincylinder, and about half-way between the feed-rolls and the periphery ofthe first worker, for the motes, seeds, and impurities to strikeagainst; but these distances may vary according to the speed of thelicker-in, the quality of the cotton, 850. The under edge of the 0card-tie or girt E is cut away at e, to allow the forward casing,adjustable plate H, and the dust-box to swing down when emptying thelatter, and to provide a suitably-sized passage for the escape of thedust and impurities.

In the above description I have called the front of the machine the endwhere the cotton fiber is fed to the card.

Having now fully described my invention, what I claim is-- r 1. In acarding-machine, the adjustable plate H, extending in front of saidmachine, in 0011].-

bination with the licker-in cylinder and cardtie, said plate beingarranged between said licker-in and card-tie, to regulate the openingunder said licker-in and to deflect impurities outwardly, substantiallyas specified.

2. In a carding-machine, the combination of the frame thereof, the frontcasing, adjustable plate H, secured to said casing, feed-rolls, andlicker-in cylinder, located and arranged sub stantially as shown anddescribed.

3. In a carding-machine, the combination of the frame thereof, the frontcasing", the feedrolls, card-tie E. licker-in cylinder B, and adjustableplate H, arranged between said cardtie and licker-in and secured to thefront casing hinged to the frame, substantially as and for the purposedescribed.

4. In a carding-machine, the combination of the frame thereof,feed-rollers, and licker'in cylinder retained in bearings upon saidframe, a front casing hinged thereto, a plate, H, made adjustable onsaid casing, and a dust-box secured to the same casing, substantially asand for the purpose described.

5. In a carding-machine, the combination of the frame thereof, a frontcasinghinged thereto under the feed-rolls, and a dust-box secured tosaid hinged casing and adapted to be partly turned over, substantiallyas and for the purose described.
